History

As with all of Kōchi Prefecture, the area of Kōnan was part of ancient Tosa Province. During the Edo period, the area was part of the holdings of Tosa Domain ruled by the Yamauchi clan from their seat at Kōchi Castle. The area was organized into villages within Kami District with the creation of the modern municipalities system on April 1, 1889. Akaoka was raised to town status on February 15, 1899, followed by Noichi on February 1, 1926, Yasu on January 1, 1943, and Kagami on April 1, 1955. The city of Kōnan was created by the merger of these four towns and the village of Yoshikawa on March 1, 2006. On the same day, the remaining municipalities of Kami District merged to form the city of Kami, and the district was abolished as a result.
